Abstract

The work studies the effect of different thermomechanical treatment regimes of Fe-Ni-Co-Ti alloy on its microstructure and mechanical properties. The characteristic temperatures of martensitic transformation, the mechanical characteristics, such as microhardness, ultimate tensile strength and ductility of martensite and austenite phases have been determined. All these parameters non-monotonously vary with the increase of plastic deformation degree. Plastic deformation under drawing results in stabilization of austenite.
